WILLIAM HARVEY, OF DENVER, COLORADO.

STONE-SAWING APPARATUS.

SPECIFICATION forming part of Letters Patent No; 651,330,dated June 5, 1900.

Application filed December 15,1898. Serial No. 699,360. (No modeh) To all whom it may concern;

Be it known that 1, WILLIAM HARVEY, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Stone-Sawing Apparatus; and I do declare the following to be a full, clear, ftIlClGXLO'D description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in diamond saws for stone-cutting apparatus; and it consists of the features, arrangements, and combinations hereinafter described and claimed, all of which willbe fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a side elevation, partly in section, of my improved stonecutting apparatus. Fig. 2 is an end elevation of the same. Fig. 3 is a fragmentary side elevation, partly in section, illustrating the automatic feed for my improved saw, the parts being shown on a larger scale. Fig. 4 is a section taken on the line at m, Fig. 3, looking downward. Fig. 5 is a fragmentary side elevation of my improved saw, the parts being shown on a larger scale than in Fig. 1. Fig. 6 is a top view of the same. Fig. 7 shows a side elevation and a section of a novel con-' struction of hinge for connecting the links or sections of my improved saw. Fig. 8 is a detail view of one of the two-part threaded sleeves through which the screw-shafts pass. Fig. 9 is atop view of another construction of saw in which double and single links or sections are alternately arranged. Fig. 10 is a perspective view showing the two members of the hinge-rivet in detail. Fig..11 is a section taken through two links of the-saw connected by a hinge-rivet.

Similar reference characters indicate corresponding parts in the views.

My improved saw consists of a series of 'ctions 5, hinged together, forming an endless chain arranged edgewise and mounted on wheels 6, whose peripheries are grooved and provided with polygonal faces to fit the link-sections. These wheels are made fast to "shafts 7, each of which is journaled in boxes 8, embracing vertical posts '9 and adapted to slide thereon to permit the necessaryvertic'al feed of the saw to keep pace with thecut during the operation of the apparatus. Each journal-box Sis connected by metal straps 1'0 with guide-collars 12, surrounding the posts 9 both above and below the journal boxes. Each of these collars, asshown in the drawings, is formed of two turning parts having ears connected together by suitable bolts. These collars are adapted to slide freely on ,the'posts 9.

The framework of thestructure consists of two posts 9, located at each end of the apparatus and connected at the top and bottom by horizontal beams 13. The two upper and the two lower collars 12 of each pair of the posts 9 are connected by bolts 14:, whose inner extremities are connected by turnbuckles 15.

Mounted on each journal-box 9 is an interiorly-threaded divided sleeve 16, through which passes a screw-shaft 17, whose extremities are respectively j ournaled in the top and bottom beams 13 of the frame.

Each extremity ofthe shaft 7 is provided with a pulley 18. One of these pulleys must be connected withany suitable motor for operating the endless saw. The other pulley will then perform the function of a flywheel.

- The screw-shaft 17 may be automatically turned for the purpose of feeding the saw as it cuts into the rockby means of pinwvheels' 7 are'turned the action of the pulleys on the pin-wheels turns the latter, together with the feed-screws 17, thus causingthe journalboxes 8, together with the shaft-wheel 7, the wheel 6, and the endless saw, to travel more or less rapidly, as may be desired, according to the qualityof the stoneand the rapidity of the saws cut.

The feed of the saw may be otherwise effected, if desired. For this purpose the screwshafts 17 are provided with miter-wheels 20, meshing with si milar wheels 21, fast on a transverse shaft 22, provided with cone-pulleys 23. One pulley on shaft 22 may be connected by a belt with a line-shaft pulley, whereby the shaft 22 may be operated and the feed-screws .turned by virtue of the connection heretofore described. The shaft 22 and the conepulleys 23 may be employed in connection and in harmony with the automatic feed mechanism. Hence it is thought properto show both constructions in the same figure.

Each link of the saw is provided with a diamond 5, (see Fig. 5,) which performs the stone-cutting function as the saw is operated. The saw-links may be provided with recesses 5", adapted to collect the sand or rock outtings and carry them out of the kerf during the operation of the saw, whereby these outtings are prevented from filling the kerf and clogging the saw.

The saw sections or links 5 may be hinged together in any suitable manner. The special construction of the hinge shown in Figs. 7 and consists of two parts 25, having beveled edges 25, each being also provided with a neck 25. Each part is further provided with an opening adapted to receive the neck of'the 'other'part. The two parts when assembled form what I term a hinge-rivet. The two saw-linksto be connected are provided with registering openings having beveled edges in which the parts of the hinge are adapted to fit. (See Fig. 11.) The two hinge parts are inserted from opposite sides and the necks riveted to hold the parts together. The links are connected by virtue of the bevel 25 of each hinge part, which engages the counterpart beveled bearing formed at the circumference of the link-opening. The two upright end frames, each composed of two posts 9 and the top and bottom beams 13, are supported by guy ropes or cables 26, connected with the posts at their upper extremities, their opposite extremities being suitably anchored. They are also further supported by similar ropes or cables 27, connected with the vertically-sliding frames, upon which the journalboxes 8 are mounted. The slack of these guy-ropes 27 should be taken up, so that the ropes will be kept reasonably taut as the saw and its supporting structure move downwardly.

In Fig. 9 a modified form of saw construction is shown, comprising two parallel links 5, connected with a single link whose extremity is inserted between them, the parts being connected by hinged rivet-s, as heretofore explained. Each screw-sleeve 16 is composed of two parts 16, provided with flanges 16, having slots 16, through which are passed bolts 16 which fasten the sleeve to the journalboxes 8. The two sleeve parts 16 are formed with flanges 16, provided with registering apertures, through which are passed the bolts of journ al-boxes embracing 16- After the saw and its supporting structu re has cut through the stone or moved downwardly to the desired limit the bolts 16 and the bolts 10- of each screw-sleeve 10 are loosened and the sleeve part l6 separated sufficien tly to release the threads of the screwshaft. The saw and the vertically-movable frame upon which it is supported may then be lifted in any suitable manner to the desired elevation preparatory to beginning the work of cutting another ker f in the rock. In this case the saw supporting frame is moved freely, since the sleeves 16 are released from engagement with the threads of the screwshaft 17. After the apparatus has been raised the sleeve parts 16 are again brought into operative relation with the screw-shafts and fastened together, after which the operation of the saw may be contin ued, asheretofore explained. A pulley 35, attached to the top cross-beam 13, may, if desired, be utilized in lifting the verticallymovable saw-supporting apparatus.

In operating the saw it is my intention to connect a pulley 18 of each shaft 17 directly with a pulley on the motor-shaft, inasmuch as the upright end frames may be separated by a considerable space, and it may not be practical to operate both shafts 7 from a single connection with the motor-shaft.

It must be understood that any number of saws of the construction shown and described may be mounted on a single supporting-frame and operated in the same manner as a single saw. In this event the shaft 7 would be provided with a number of wheels 6 instead of a single wheel, as shown in the drawings.

Having thus described my invention, what I claim is 1. A stone-saw comprising a series of flat links and hinge-rivets connecting the links forming an endless edgewise-flexible instruinentality, the links having recesses formed in their cutting edges which are provided with diamonds for the purpose set forth, each rivet being composed of two parts having beveled outer edges, each part being apertured to receive a riveting-neck formed on the other part,the said riveted parts beinginserted from opposite sides in openings form ed in the links to be connected, the said openings having counterpart beveled edges to engage the beveled edges of the riveted parts.

2. An endless stone-saw comprising a series of apertured links and hinge-rivets connecting the links, each rivet being composed of two parts having beveled outer edges, each part being apertured to receive a rivetingneck formed on the other part, the said rivet parts being inserted from opposite sides in openings formed in the links to be connected, the said openings having counterpart beveled edges to engage the beveled edges of the riveted parts.

3. The combination with a porting-frame, provided with suitable supupright posts, the posts and IIO . the journal-boxes and connected with said boxes, a suitable transverse connection be-- tween the opposite collars of two adjacent posts, screw-sleeves made fast to the journalboxes, vertical screw-shafts journaled in the frame and engaging said sleeves, means for turning the screw-shaft, transverse shafts journaled in the said journal-boxes, wheels mounted on the transverse shafts, an endless edgewise-fiexible saw mounted on the said wheels, means for rotating the transverse shafts whereby the saw is actuated and means mounted on the screw-shafts and actuated from the transverse shafts for imparting an intermittent turning movement to the screwshafts.
